What's so special about the tire repair of a passenger car? When the tire is damaged, in the end is the compensation or the change? At present, 60% of users are unaware of this problem. In the end, it is necessary to make up for the change, which requires professional analysis and judgment. For commercial vehicle tires, the repair range is wider than that of passenger car tires. In addition to the crown, the shoulder and sidewall parts can be repaired.

Why do professional repairs? In the current market, the most common repair method for commercial vehicle tires is fire repair. It uses high-temperature and high-heat methods to fuse raw rubber into the wounds of tires and fuses the tire wounds with rubber. The method of repairing fire is the most popular patching method on the market, but it is not the perfect patching method. There are a series of inadequacies. First of all, the way to make up the fire must go through high temperature, and the high temperature will cause the rubber of the tire to age and reduce the service life of the tire. Secondly, it will break the structure of the tire. There is a safety hazard; third, the way of fire repair cannot effectively repair the tubeless tire. In the end, the tire after fire repair cannot be refurbished.

Based on the shortcomings of fire compensation, Michelin has innovated tire repair methods and formed a unique professional repair method. The professional patching is firstly based on the fact that the patch is small and only applies to the partial vulcanization of the wound, so that the tire maintains its overall heat dissipation balance. Then the curing strength at low temperature is basically close to the hardness of the carcass rubber of the tire itself. The new patch can form a good one with the tire to ensure the repair effect. The curing effect of professional repair, the compactness and wear resistance of the rubber have reached the best results, and the impact on the service life of the tire has been minimized.

Michelin conducts professional skills training and professional knowledge dissemination through the card bus tire repair national competition. Michelin adopts a one-to-one or one-to-two training mode for training participants to provide repair technical explanations and practical training. At the same time, professional technical manuals, video CDs, and promotional videos and other materials are introduced to help technicians further To improve repair technology, after many years of insistence, more and more card and passenger car users have realized the importance of tire repair. Li Ling introduced that in 2013 China's card and passenger car market, the demand for professional service for tire maintenance increased by nearly 250% compared with 2012.

The National Bus & Coach Tire Repair National Competition not only pays attention to the assessment of tire repair technology, but also puts forward high requirements for each contestant's patching process. The competition is aimed at the fourth item, which is the main content of the assessment. A total of 18 assessment points are set up, and in particular, the relevant procedures for grinding and wound treatment are specified in detail. For example, the use of low-speed grinders and high-speed grinders in different situations, cleaning of the inside and outside of the wound, wound identification and measurement, filling of the inner and outer wounds, and an estimate of the final curing time Judging the technical level and operating specifications of technicians.

Li Ling, director of commercial vehicle marketing for Michelin (China) Investment Co., Ltd., said that the quality of professional services will directly affect the operational safety and efficiency of use. Professional services not only include tire repair technology, but also include a complete set of professional service processes. Because the specification of the process will also directly affect the tire repair effect.
